摘要： A peristaltic pump rotor comprising a body, an arm pivotally mounted to the body at an arm- body pivot point, the arm being movable between a deployed condition in which the arm is arranged, in use, to contact tubing in a peristaltic pump so as to effect pumping, and a retracted condition in which the arm is withdrawn from the tubing so that pumping is not effected; an actuator for effecting movement of the arm between the deployed and retracted conditions, the actuator comprising a first link pivotally mounted to the body at one end thereof and to a second link at the other end thereof, the second link being pivotally mounted to the first link at one end thereof and to the arm at the other end thereof at a point on the arm spaced from the arm-body pivot point; the links and pivot points being arranged such that the arm is retained in the deployed condition by the first and second links being arranged over centre when the arm is in the deployed condition.
